SINGLE SUPPLY 1:9
PECL-TO-TTL
SY100H641
FEATURES
DESCRIPTION
■ Input frequencies up to 135MHz
■ PECL-to-TTL version of popular ECLinPS E111
■ Guaranteed low skew specification
■ Latched input
The SY10/100H641 are single supply, low skew
translating 1:9 clock drivers. Devices in the Micrel-
Synergy H600 translator series utilize the 28-lead PLCC
for optimal power pinning, signal flow-through and
electrical performance.
■ Differential internal design
The devices feature a 24mA TTL output stage with
AC performance specified into a 50pF load capacitance.
A latch is provided on-chip. When LEN is LOW (or left
open, in which case it is pulled LOW by the internal pull-
downs), the latch is transparent. A HIGH on the enable
pin (EN) forces all outputs LOW.
■ VBB output VECL for single-ended operation
■ Single +5V supply
■ Reset/enable
■ Extra TTL and ECL power/ground pins
The 10H version is compatible with MECL 10KH ECL
logic levels. The 100H version is compatible with 100K
levels.
■ Choice of ECL compatibility: MECL 10KH (10Hxxx)
or 100K (100Hxxx)
■ Available in 28-pin PLCC package
